title: Pseudouridine and beta-aminoisobutyric acid excretion in urine: diagnostic and prognostic value.
abstract: The sex- and age-related urinary excretion of pseudouridine/creatinine and beta-aminoisobutyric acid/creatinine was studied in 77 healthy subjects (24 children and 53 adults, 27 of whom were women). The highest values were found in the youngest children. We compared the excretion ratios of pseudouridine/creatinine and beta-aminoisobutyric acid/creatinine in women and men and found no significant differences between them. The excretion patterns may be helpful in the diagnosis of patients with urinary tract tumours and in predicting patients at risk of recurrences.
